It does not matter how many fonts support both (LM does, and
Libertine). One feature of a BibTeX file is reusability for many
documents, and when the file is created you do not know what will be
the default emphasis of the document. By explicitly coding \it, you
are assured that the italic face will be attempted. If it is not
available, there should be an error message, and you can then have a
discussion with your editor. The claim of the new bibliography
subsystem is that it will implement APA strictly, and that calls for
italic.
I understand as well that \em allows switching (reverse emphasis as
noted above). It also provides some italic correction. I am asking
about the appropriate use of the two variations of \em: \emph (which
is a grouped command \em) and \emphasized (defined as
\bgroup\em\let\nexttoken). I understand and make use of grouped
commands -- they are largely syntactic sugar, but I like sugar. I am
less certain of the purpose of \emphasized, how it works, and why it
might be useful. I do not recall seeing a command definition with a
bgroup and no egroup before.
\em -> {\em ...}
\emph -> \emph{...} or {\emph ...}
\emphasized -> \emphasized{...}
